Sharing her pictures

I really love sharing pictures of my girlfriend. I have shared a few with some people online and it turns me on so much thinking someone is enjoying her body. And she doesn't know. I've asked her about having a threesome with another guy and she's not against. But what I want to see is someone f****** her without protecting and filling her up with their seed and getting her knocked up. Just makes me so turned on thinking of another man shooting his load into her.
